ABB ACS850 User Manual

142 Parameters
Spd ref Safe The drive generates an AI SUPERVISION alarm and sets the
speed to the speed defined by parameter 30.02 Speed ref
safe.
WARNING! Make sure that it is safe to continue
operation in case of a communication break.
2
Last speed The drive generates an AI SUPERVISION alarm and freezes
the speed to the level the drive was operating at. The speed
is determined by the average speed over the previous 10
seconds.
WARNING! Make sure that it is safe to continue
operation in case of a communication break.
